Severe! UTI infection with NO pain?!!!

Is it really possible to have a UTI that put me to bed for a week thinking it was flu...... With absolutely NO pain....... Never heard of such

What i had. UTI with no pain but had a fever of 103 degrees.

I've I used to take care of elderly one lady kept getting a uti with no pain or even knew she had it. It happens as you get older I guess

yes my aunt and my hubbys employer were bed ridden with it, they are both over 60
